Porsche motorsport

Porsche has been successful in many branches of motorsport of which most have been in long distance races.

Despite their early involvement in motorsports being limited to supplying relatively small engines to racing underdogs up until the late 1960s, by the mid-1950s Porsche had already tasted moderate success in the realm of sports car racing, most notably in the Carrera Panamericana and Targa Florio, classic races which were later used in the naming of street cars. The Porsche 917 of 1969 turned them into a power house, winning in 1970 the first of over a dozen 24 Hours of Le Mans, more than any other company. With the 911 Carrera RS and the Porsche 935 Turbo, Porsche dominated the 1970s, and even has beaten sports prototypes, a category in which Porsche entered the successful 936, 956 and 962 models.

Porsche is currently the world's largest race car manufacturer. In 2006, Porsche built 195 race cars for various international motor sports events, and in 2007 Porsche is expected to construct no less than 275 dedicated race cars (7 RS Spyder LMP2 prototypes, 37 GT2 spec 911 GT3-RSRs, and 231 911 GT3 Cup vehicles).

Porsche regards racing as an essential part of ongoing engineering development—it was traditionally very rare for factory-entered Porsche racing cars to appear at consecutive races in the same specification. Some aspect of the car almost invariably, was being developed, whether for the future race programs or as proof of concept for future road cars.

As Porsche only had small capacity road and racing cars in the 1950s and 1960s, they scored many wins in their classes, and occasionally also overall victories against bigger cars, most notably winning the Targa Florio in 1956, 1959, 1960, 1964, and every year from 1966 to 1970 in prototypes that lacked horsepower relative to the competition, but which made up for that, with reliability, low drag, low weight and good handling.

In their September 2003 publication, Excellence magazine identified Lake Underwood as Porsche's quiet giant in the United States and he is among the four drivers, including Art Bunker, Bob Holbert, and Charlie Wallace who are identified by the Porsche Club of America as having made Porsche a giant-killer in the USA during the 1950s and early 1960s. Notable early successes in the USA also included an overall win in the 1964 Road America 500 for an under-2-litre RS-60 driven by Bill Wuesthoff and Augie Pabst.
